How to Make Tennessee Onions
-
Prep Onions: Start by peeling and carefully slicing the Vidalia onions into ¼-inch thick rounds. This thickness ensures they caramelize evenly and develop that delicious sweetness.
-
Melt Butter: In a large skillet, heat the unsalted butter over medium heat until it’s bubbly. This creates the perfect base for our onions and adds rich flavor to the mix.
-
Season Onions: Once the butter is melted, add the sliced onions to the skillet. Sprinkle in salt, garlic powder, and oregano, then stir them all together until the onions are well coated with the seasoning.
-
Caramelize: Cook the onions for about 20-30 minutes, stirring occasionally. You want them to turn a beautiful golden brown and become tender. Keep an eye on them to prevent burning!
-
Add Cheese: Remove the skillet from heat and generously sprinkle the shredded Italian blend, cheddar, and parmesan cheeses over the warm onions.
-
Melt Cheese: Cover the skillet with a lid, allowing the residual heat to melt the cheese beautifully. This will create that irresistible gooey texture before serving.
Optional: For an extra touch, drizzle with a little balsamic reduction just before serving.
